Same OS = no interest from me. If none of the alternatives (Honeycomb, WebOS, Blackberry) meet/beat the iPad in price, then I'm just out of the tablet game. I have no interest in staring at endless grids of icons with a ton of dead/negative space on the screen. Give me the ability to view essential information at a glance without having to open one app for my calendar, another app for my mail, etc, and you start piquing my interest.
Bumped specs for the same user experience is pointless to me. Apple, stop making the devices thinner and start paying attention to updating the OS.
Also, Microsoft had wireless syncing with Zune from very early on, so Apple shouldn't receive any special praise for bringing this feature to iTunes, but they will by all the press, of course.
